Over time, everything changes. Climates change, species evolve, ecological systems change, and so forth, and a species that was well adapted to a particular ecological niche may eventually find that its niche disappears or changes to the point at which that species is no longer adapted to it.
What else can I help you with?
How do you know a mass extinction actually did occur?
No evidence of the extinct lifeforms appears in the stratigraphic record immediately following the extinction event.
When did the Cretaceous Tertiary extinction occur?
About 65.5 million years ago. The Cretaceous and Tertiary are geological time periods either side of this event. The event is significant because there was a large mass extinction event at this time including the extinction of all non avian dinosaurs. Most experts agree that the cause of the extinction was a asteroid impact.
Where does extinction happen?
Extinction happens when an endangered species is completely wiped out by human activity or natural disaster for example:- the Ice Age when the mammoths and the other animals which went extinct at the same time
What processes must occur to produce an igneous rock?
What processes must occur to produce an igneous rock
What gas must be present for a combustion reaction to occur?
Oxygen gas must be present for a combustion reaction to occur.
When doe extinction occur?
Extinction of a single species can occur at any time if said species in hunted excessively, but mass extinction only occurs every 27 to 33 million years.
When the ucs is removed and the cs is presented alone for a period of time what will occur?
extinction
Why do you think most extinction's occur as background extinctions?
Most extinctions occur as background extinctions because they are longer time periods unlike the shorter mass extinctions which there were only two in the Paleozoic era, the Ordovician mass extinction, and the Permian/Triassic extinction in which 95% of all marine animals became extinct
When does the sixth extinction occur?

How far are butterfly extinction?
butterfly are not close to extinction they must be in hot climate to live if not they will die

Most experts agree that the cause of the extinction was a asteroid impact.
What is background extinctions?
A background extinction is the continuous extinction of individual species caused by climate change, disease, loss of habitat, and competitive disadvantages against other species. Background extinctions occur at a slow rate over time, affecting only a few species at one time.
What are 3 reasons for mass extinction?
Mass extinction could occur due to climate change, an asteroid impact and even a volcanic eruption.
When did the last mass extinction occur in years?
65 million years ago
What is likely to occur when an endangered species has low offspring numbers?
Extinction is likely.
Does extinction occur today?
Some or several species become extinct every day.
